List of countries by population in 2000

This is a list of countries by population in 2000.

It is a list of countries in the world by population in the exact beginning of the year 2000.

Because the table contains data only for the 230 nations and territories at the start of 2000, there are no entries for national regions declared later in 2000 or subsequent years.

This list adopts definitions of "country" on a case-by-case basis.

The United Kingdom is considered as a single country while constituent countries of the Kingdom of the Netherlands are regarded separately.
